Dishonest price increase on older laptop memory

I am not a person that likes to leave a bad review. Especially a 1 star rating but if you are dishonest then we are going to have a problem.

I was looking for memory for a laptop. It is a little rare memory but I knew Partmaster will have the memory needed. I send them an Email for a price and delivery. They send me a quotation, R425 with delivery. The memory is for an older lady so she had to save a little bit.

Was past a week and a quotation is only valid for 7 days. So I asked for a new Quotation. They had it over R700. I send them an email and asked how this is possible. They did not respond. I spoke with the lady and she said it is fine but she has to save a little bit. I though I will help her. I am not well off but we needed memory as it only has 4GB It was again past a week asked them just to resend a quote. They had it at R1100. This is from R400 to over R1000 in 3 weeks

I know higher up DDR4/DDR5 did slightly go up in price but this should have No effect on DDR3 that is like 12 years old. This is dishonest as they know it is rare and try to milk people. As much as I need the memory. I will not pay for DDR3 the same price as DDR4 memory.

Sorry, I will never contact them again as this is very bad business Practice.
